' INSULATING COMPOSITION.

To all whom it may concern:

Be it known that I, :WILSON H.'STRICK- LER, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a new and useful Im rovement in anInsulating Composition, 0 which the following is a specification.

This invention relates to an insulating composition composed of fibrous asbestos, comminuted mica, a double silicate of soda, and a thorough insulation, and will resist any andall concussion and vibration imparted to the metal thus insulated and can be applied as conveniently and effectively in repairs as in original application.

manufacturing my composition I use asbestos sufliciently pulverized yet possessing sufiicient length of fiber to neutralize and overcome the inflexibility of the laminated nature of the mica. The mica is comminuted and varies in degree of comminution, dependent upon the requirements of the uses to which the article is to be placed, as can also the amount of mica and asbestos used, dependent upon the increased need for insulatlon pro erties, as can also the disposition on the s ace of the metal varyas to the 10- cation of the asbestos and the mica, dependent upon the requirements of the case.

The composition is as follows: The combination of a thirty-per-cent. silicate of soda with asbestos and mica as I use it avoids objectionable features of unpliability heretofore found in insulating materials in which the silicate forms a part. The silicate before ap lication and use is created a double silicateby the addition thereto and thorough incorporation thereof of about fifteen to twenty per cent. of a strong solution of lime, thereby making the silicate im ervious to water or any chemical change. he silicate Specification of Letters Patent.

is also treated at the same time and in the same manner to a strong solution of best soap shavings, (dissolved in hot Water,) the per cent. of incorporation beingthe s ame namely, about fifteen or twenty er cent.-

which che ically changes its sti characteristic into p 'ability.

The met llic surface is first coated with the silicate thus prepared, over which is then given a coating of the asbestos, which is then allowed to dry, after which'a coating of the prepared silicate is again given over the asbestos covering, which is then given a coating of comminuted mica. After this has dried as many additional coatings of the mica and asbestos may be given it as may be desired, dependent upon the insulating eflect and insuating property needed.

- An outslde or finishing covering or coating of paint or liquid tar paint neutralized with a strong ten-per-cent. lime solution, or any desired outside covering may then be given to it.

The advantages of an insulation of this kind direct to metallic surfaces lies in its superior insulation, combined with the low cost of. manufacture, convenience in. application, and resistance to water, concussion, and vibration.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

- 1. An insulating material formed of comminuted asbestos comminuted mica, double silicate of soda and a solution of soap.

2. As a new article of manufacture, an insulation com osed of a coating of silicate of ,soda, create a double silicate by the addition and inco oration of a solution of lime,

to which is a ded by incorporation a solu-' tion of soap, pkulverized asbestos and mica,

incorporated t erein as described.
